SIM Lock

If your SIM does not work when you first enter it into your mobile and after entering your PIN, it may have a SIM lock. If you have been with your current provider for more than 1 year this lock can be removed for free, please contact your current provider directly to request the code which will allow you to remove your SIM lock.


SIM Card Validity Period

If you do not make any calls or SMS within a 3 month period your credit will be frozen. If your credit has been frozen you have one month in which to top up again, in which case your old credit will be reinstated. If you do not top up within this period your number will be frozen permanently and you will not be able to use your SIM


PIN & PUK Codes

If you enter the wrong PIN code three times your SIM card will automatically lock. In this case you must enter your PUK code. Your PUK code is displayed on the SIM card Letter found in your starter pack. Please retain it for safe keeping. If you can’t find your PUK code call Customer Services.
